Duct leakage and leakage testing.

Author(s) : WILLS I.

Type of article: Article

Summary

Although air leakage from ducts has previously been treated as insignificant and leakage testing as not cost effective, this paper demonstrates that even minor leakage can have a significant effect on plant energy consumption and greenhouse gas emissions. Recognising this, the recently published AS 4254.2:2012 reverses past practice and now mandates leakage testing of systems over 3000 L/s. Not only will reducing leakage reduce energy use and greenhouse gas emissions producing a better outcome for the building owner and community, but attention to issues raised in this paper will benefit the contractor by reducing or eliminating the need for costly rectification of leaks revealed by leakage testing. The paper examines the implications of the Standard’s testing requirements and suggests extension of its scope.
